(An arcsecond is 1/3, 600 of a degree and is equivalent to the width of a dime as seen from a distance of two kilometers.)
The dishes will be movable, allowing baselines from 150 metres to 18 kilometres, with the longest baseline and the shortest wavelength giving resolution as fine as 0.005 arcsecond, a factor of 10 better than Hubble.
By combining the light from four telescopes, the European Southern Observatory Very Large Telescope Interferometer (VLTI) delivers angular resolution at milli - arcsecond scale and astrometry at tens of micro-arcsecond.
Abstract: We present the discovery of 61 wide (> 5 arcsecond) separation, low - mass (stellar and substellar) companions to stars in the solar neighborhood identified from Pan-STARRS \, 1 (PS1) data and the spectral classification of 27 previously known companions.
Fomalhaut moves across the sky at 0.425 arcseconds per year, which is the apparent width of a penny seen from five miles away.
The extremely dim companion object was observed to share the same high proper motion as Epsilon Indi — around 4.7 arcseconds per year — from the perspective of an observer in the Solar System.
Then the middle image shows how if we remove (in real time) the blurring of the atmosphere with MagAO's adaptive optics» the resulting photo becomes ~ 17 times sharper (corrected resolutions range from 0.019 - 0.029 arcseconds on theta 1 Ori C).
MagAO's photo shows that a pair of stars some 7 arcseconds away from Theta 1 Ori C was heavily distorted into «teardrop» shapes as the strong UV light and wind create shock fronts and drag gas downwind of the star, a very rare example of a low mass pair of young disks.
This image with 0.1 arcsecond resolution from the Swedish 1 - m Solar Telescope represents the limit of what is currently possible in terms of spatial resolution.
On the other, the Hipparcos Space Astrometry Mission (1989 - 93) failed to detect significant astrometic motion resulting from a major close companion as small as 0.5 Solar - mass between 11 AUs (one arcsecond) and 0.35 AU of the star (Akeson et al, 2009).
«We, for the first time, can make deep images that resolve objects just 0.02 arcseconds across — this is a very small angle — it is like resolving the width of a dime seen from 100 miles away, or like resolving a convoy of three school busses driving together on the surface of the Moon.»
Viewed from another star, our Earth's reflected light would be 10 billion times fainter than the Sun itself, with an orbit that separates the Earth from the Sun by a tiny fraction of an arcsecond.
